Decide what to do with the flashing script
Having a hard-coded version of the flashing script in the board directory is very helpful. The challenge comes from keeping that script up-to-date for all the various targets and pushing it upstream.
I think keeping the script in the directory until the upstream Zephyr maintainers weigh-in is the right approach, however, I'd like to work towards making each version the same script.
I'll be working on that script here: https://git.beagleboard.org/jkridner/cc2538-bsl
